Description

HYDROELECTRIC GENERATOR INSTALLED IN WATER THAT FLOWS TECHNICAL FIELD The present invention relates to a hydroelectric generator installed in flowing water, and more particularly, to a hydroelectric generator installed in the flowing water, capable of generating electricity (energy), when installed in a current river, in response to the flow of the water that is allowed to enter the generator.

BACKGROUND OF THE INVENTION General methods of generating electricity (energy) include the generation of hydroelectric energy (water energy) using hydroelectric energy, a generation of thermal energy that uses fossil fuels, an atomic power generation that uses nuclear energy and the like.

These generation methods require large-scale generation facilities, and a large number of energy sources to operate generation facilities, and have limits on installation spaces. Especially, due to the high dependence on fossil fuels such as oil and coal, the energy sources used for the generation of thermal energy, in comparison with other fuels, the generation of thermal energy causes problems such as depletion of resources . The generation of thermal energy also has a problem in that it is not friendly to the ecosystem, which refers to air pollution and radiation leakage, and has a limit on permanent use due to limits on resources for generation of energy.

Consequently, to prevent the depletion of resources due to the use of oil or coal, various disasters due to global warming, which is caused as a result of the ignition of oil or coal, and environmental pollution due to various pollutants, Energy-generating methods, which are environmentally friendly using natural energy such as solar energy, tidal energy, wave power, wind and hydroelectric energy and capable of permanently using energy sources, have recently been developed and applied.

Among others, the methods of generating energy for converting solar energy or wind into electrical energy and storing electrical energy in a rechargeable battery and the like have considerable limits on climate and environments. Also, tidal generation is merely applicable to locally limited sites because it is capable of generating electricity only when it is installed in an area with a large difference between low and high maras. Similar to tidal generation, a generation by the force of the waves can be applied only to limited sites where the waves are continuously formed, so that it also has the limit on the installation sites.

A generation of hydroelectric power requires lakes or reservoirs that store a large amount of water. Consequently, the generation of hydroelectric power is also applicable only to limited spaces. The generation of hydroelectric power also has a limit on the installation space. However, generators that use hydroelectric power provide advantages since a maintenance cost is rarely required once it is installed, and electricity can be generated stably and semi-permanently.

Meanwhile, a general hydropower generator generates electricity by spinning turbines through the use of the gravitational force of falling water from a high position. The general hydropower generator thus has an installation problem, since it requires the construction of relatively large-scale facilities, such as water storage facilities, generation facilities that are installed on the downstream side of a dam, and drainage facilities to discharge the water used for power generation to the river or to the sea.

The hydroelectric power generator of the related art has a limit in that the efficiency of operation of the generator is decreased during the period of water scarcity or drought for which the water is not completely stored in the water storage facilities.

To convert the energy of the tides with a low flow velocity or energy from the water flowing from the river into driving energy, the fins to which such energy is transferred from the flowing water, have to be of large size and large number .

Such a hydroelectric power generator has been described in Patent No. 534546. In the invention, a rotating body is installed on an endless belt, which is installed in parallel to a water flow direction, and a motor is driven using the rotational force of the body of rotation. Here, the rotation body is installed on the endless belt, it includes a plurality of fins, specifically, plates on which the water is shocked. The plurality of fins to receive the force of the flowing water are aligned in the same direction as the flow direction of the water. Consequently, the fins located on the back receive a force of flowing water that has been diminished by the fins located on the front. Therefore, the use of the force of flowing water is not economical.

DESCRIPTION PROBLEM, TECHNICAL The present invention has been made having in mind the drawbacks of the related art, and an object of the invention is to provide a hydroelectric generator installed in the flowing water, capable of increasing the generation efficiency, by means of generating a current of water in the form of a whirlpool by allowing the introduced water to be turned, making the water flow faster by allowing the flowing water to be rotated to a water outlet through a spiral water movement channel , and by rotating the flap plates of a fin by the water pressure which is continuously advanced due to the rapid current of the water.

Still another object of the invention is to provide a hydroelectric generator capable of stably generating power by the fixed installation of the generator in a lower portion of a stream, a river or an irrigation channel with a flowing water velocity, to prevent the destruction of an ecosystem in the water, such as the migration of fish, without interfering with the flow of water, to be environmentally friendly, and less restricted by conditions such as a place of installation and the like, and to properly manage the changes in a stored state of water and the like, regardless of the change in a water level.

ADVANTAGE EFFECTS As described above, the hydroelectric generator according to the present description can be installed in the lower portion in the flowing water, to cause the water to swirl. This can generate a flow velocity faster than that of the flowing water, thus increasing the generation efficiency.

Also, when a centrifugal force is applied to the water through the water movement channel, the water can be rotated with formation of the vortex to flow thus at a fast speed. Also, while the water is turned rapidly, water can continue to hit a fin, resulting in additional increase in generation efficiency.

The central cylindrical portion that is hollow can induce smooth rotation of the fin and the fin plates can be made of carbon fibers that have a relatively higher weight than water to be rotated without weight resistance, separated.

The channel part formed on the upper part of the body can provide an installation space for the generator. Also, an internal space of the channel part may have a form in which a center is low and an external side is high, which may facilitate the water being turned outward.

The inflow water induction body can induce flowing water to be effectively introduced into the body, and the rotatable expanded tube can change the flow of water in a spiral form while it is rotated, such that water can be introduced with formation of a whirlpool.
